Don't read character set files if we are using only the default charset. In most cases the user will not anymore get a warning about missing character set files Compare strings with space extend instead of space strip. Now the following comparisons holds: "a" == "a " and "a\t" < "a". (Bug #3152). Note: Because of the above fix, one has to do a REPAIR on any table that has an ascii character < 32 last in a CHAR/VARCHAR/TEXT columns. heap/hp_hash.c: Comments and DBUG information include/my_handler.h: Updated prototype for mi_compare_text myisam/ft_boolean_search.c: Updated calls to mi_compare_text myisam/ft_nlq_search.c: Updated calls to mi_compare_text myisam/ft_parser.c: Updated calls to mi_compare_text myisam/ft_stopwords.c: Updated calls to mi_compare_text myisam/ft_update.c: Updated calls to mi_compare_text myisam/mi_check.c: Updated calls to mi_compare_text myisam/mi_search.c: Changed all string comparisons that removed end space to instead extend the shorter string with space myisam/mi_unique.c: Updated calls to mi_compare_text myisam/mi_write.c: Updated calls to mi_compare_text myisam/myisam_ftdump.c: Removed compiler warning mysql-test/r/ctype_collate.result: Fixed wrong result mysql-test/r/heap_btree.result: More tests mysql-test/t/heap_btree.test: more tests mysys/charset.c: Don't read charsets if we are only using default charset Don't require 'init_available_charsets' to succeed. mysys/my_handler.c: Compare strings with space extend instead of space strip mysys/tree.c: Fixed code to get better results for range optimzier sql/field.cc: Compare strings with space extend instead of space strip sql/filesort.cc: Compare strings with space extend instead of space strip sql/ha_heap.cc: Created bit map for keys that are using BTREE.
